Abstract

A fiber-optic-bundle-based optical coherence tomography (OCT) probe method is presented. The experimental results demonstrate this multimode optical fiber-bundle-based OCT system can achieve a lateral resolution of 12 microm and an axial resolution of 10 microm with a superluminescent diode source. This novel OCT imaging approach eliminates any moving parts in the probe and has a primary advantage for use in extremely compact and safe OCT endoscopes for imaging internal organs and great potential to be combined with confocal endoscopic microscopy.

摘要

提出了一种基于光纤束的光学相干断层扫描（OCT）探头方法。实验结果表明，这种基于多模光纤束的OCT系统在使用超发光二极管光源时，横向分辨率可达12微米，轴向分辨率可达10微米。这种新颖的OCT成像方法消除了探头中的任何运动部件，在用于对内部器官成像的极其紧凑且安全的OCT内窥镜方面具有主要优势，并且具有与共焦内窥镜显微镜相结合的巨大潜力。
